Cephalic dorsum to level of posterior margins of eyes with sharply defined microreticulate ground sculpture between larger foveolate punctures. Eye tends to be slightly farther forward in  elegans(EP 0.74–0.84) than in  grandidieri(EP 0.80–1.00). In full-face view sides of head often, but not always, with a very few short, projecting setae. Mesotibiae and metatibiae usually without standing setae, but one or two may be present (for instance, one is present on left mesotibia of holotype). AII longer than broad in dorsal view; AIII as broad as long to slightly longer than broad. Tergites AII to AIV usually with 1–2 pairs of setae anteriorly and sometimes 1–2 pairs near posterior margin of each segment, but numbers are variable and some abrasion is suspected. In the type-series sternites of AII–AIV have no setae, or at most have 1–2 short setae close to the posterior margins; setae on these segments are generally more apparent in the non-paratypic material. Dorsum of mesosoma usually retains at least traces of microreticulate ground sculpture, but this is generally more feebly developed than on the head between the eyes.   Holotypeworker (top specimen of three on pin),  Madagascar: Prov. Mahajanga, P.N. Baie de Baly,  12.4 km337° NNW Soalala,  10 m, 16°00.6’S, 45°15.9’E,  26-30.xi.2002, BLF#6890, ex dead twig above ground, tropical dry forest, CASENT0492213 (  B.L.

Two workers mounted on same pin below holotype; two workerswith same data but CASENT0492214 ( CASC).   S. elegansexhibits the same size-related variation that is shown by  grandidieri. Within the type-series HW varies from 0.58 to 0.74 and CI from 66 to 71.   Non-paratypic material examined.  Madagascar: Prov. Antsiranana, Forêt Anlabe, ENE Daraina ( B.L.
